No blacklisted players. In the past seasons some owners have used Joss and I'm sure some of the other cookie monsters. The league is typically very competitive with most teams in the race until late in the season. Of course there is always the chance that some teams will dominate but that seems to be the norm in most of the leagues I have played in - if you put together a very good team for the ballpark you have selected it seems like you do fairly well.
